Rotary roller vibrators for concrete compacting and hopper emptying
Achieve higher compaction and efficient emptying with rotary roller vibrators, perfect for reducing downtime in high-speed operations while maintaining structural integrity in concrete and similar applications.

The Rotary Roller Vibrators OR from WAMGROUP offer a robust solution for industries requiring precise vibration in compacting and material handling. These vibrators operate by moving rollers inside an eccentric guide, generating high-frequency, low-amplitude vibrations ideal for tasks such as concrete consolidation and foundry mold vibration. Available in four sizes and constructed with a durable black aluminum casing and brass cover, they are engineered to function efficiently with oiled air at 2 to 6 bar (29 ~ 87 PSI), making them suitable for explosive environments as per ATEX EX II 2DG cT(x) standards. With applications spanning construction, food processing, and chemical industries, the OR-series excels in handling diverse production challenges, from compacting concrete slabs to processing refined sugar. Despite operating noise reaching 90 dB(A), these vibrators offer high centrifugal force and easy installation, ensuring seamless integration into existing production lines. Optional customization and engineering support enable tailored solutions to meet specific operational needs.
